ABSTRACT:
An acrylic rubber composition is proposed which is improved in respect of the extrusion-moldability as well as the surface slipperiness of the vulcanized article obtained therefrom. The composition comprises (a) an acrylic rubbery cooplymer which is a copolymer of a (meth)acrylic ester and a coolymerizable organosilicon compound having a silicon-bonded vinyl group in a molecule, (b) a reinforcing filler, (c) a powder of spherical particles having a specified average particle diameter and (d) an organic peroxide as a vulcanizing agent. The composition can be compounded further with a blowing agent to give a foamable rubber composition capable of being vulcanized into a spongy rubber body exhibiting excellent feeling on touch and slipperiness in contact with human skin to be useful, for example, as a material of cosmetic puffs.
